“Luckily we had not allowed guests in to ride yet but those of us present at the time all agreed that this was a potentially fatal flaw.”

Because of this incident, safety procedures were improved after a thorough investigation. However, Jon Armstrong believes that there should have been an automatic shutdown if the raft didn't move up the conveyor belt.

He added, “I doubt I’d go on that ride until they changed the format. It needs a redesign.”

The Daily Telegraph reports that the group involved in the tragedy were just five seconds from safety as the ride was coming to an end before the craft flipped, drowning two of the adults, crushing the other two on a conveyor belt, but somehow miraculously throwing the two children to safety.

Police worked through the night, investigating the incident, looking for clues which helped them understand why the ride malfunctioned and said during a press conference that it was a "miracle" the children survived.
